理论预测，完全方位对称的非中性等离子体陷阱应该会永远限制等离子体。无意中的陷阱不对称被认为限制了等离子体的约束时间小于-lt；105 S。故意施加的静电场破坏了方位对称性，影响了等离子体的约束时间。虽然小的刻意的不对称不会显著降低陷阱的约束特性，但大的不对称会显著降低等离子体的约束。本文研究了这种降解的标度规律。当故意应用不对称性时，等离子体损失的机制似乎发生了变化。
Theory predicts that perfectly azimuthally symmetric non‐neutral plasma traps should confine plasma forever. Unintentional trap asymmetries are believed to limit plasma confinement times to less than <105 s. Deliberately applied electrostatic fields break the azimuthal symmetry and affect the plasma confinement time. While small, deliberate asymmetries do not significantly reduce the trap’s confinement properties, large asymmetries significantly degrade the plasma confinement. The scaling laws of this degradation are studied herein. The mechanism of plasma loss appears to change when deliberate asymmetries are applied.
